the guide chart. It is too inexact to give to artillery the exact
position of a new objective precisely located by an infantry
observer a~nd not yet plalcced. In this case recourse shouldl be

position of the observed point: should be indicated in p~encil.
Every officers should k~no~whow: First, to locate on the guide
plan any point whose coordlinates are given h~im; secondl, to find
the coordinates of any point; whatever that is not alreadly numnbared

of locating wsith some precision a point to wvhich· he wiishes to
attract; attention.
